Answer: .81 or .82

Step-by-step explanation:  

Answer: Cost of a side dish = $ 7

Cost of a roll = $1

Cost of prime rib = $21

Step-by-step explanation:

Let x = cost of a side dish , y= cost of a roll

Then, cost of a prime rib = 3x

Jackie's meal : prime rib, 2 side dishes, and a roll, it came to $36

i.e. 3x+2x +y = 36

⇒ 5x+y=36   (i)

Ted's meal : prime rib, 3 side dishes, and 2 rolls, it came to $44.

i.e. 3x+3x +2y = 44

⇒6x+2y=44

⇒ 3x+ y= 22   (ii)  [divide both sides by 2]

Subtract (ii) from (i), we get

2x= 14

⇒ x=7               [divide both sides by 2]

Put x=7 in (ii), 3(7)+y=22

⇒ 21+y=22

⇒  y =22-21

⇒ y= 1

So, cost of a side dish = $ 7

cost of a roll = $1

cost of prime rib = 3x $7 = $21

Answer:

one dozen: 12 servings

four dozens: 12x4 so 48 servings

Step-by-step explanation:

Assuming one cookie is one serving a dozen would be 12 so 12 servings per dozen.

Answer:

48 cookies

Step-by-step explanation: so a dozen cookies would be 12 cookies and 4*a dozen which would be 12 is 48 so 48 cookies= 4 dozens

Answer:

y= 1/3x-3

Step-by-step explanation:

rise /run

-3 is the point you start

Answer:

y = 1/3x - 3

Step-by-step explanation:

First, find the slope

(3, -2)

(0, -3)

-2-(-3) = 1

3 - 0 = 3

Slope = 1/3

Now, find the y intercept

y = mx + b

-2 = 3 * 1/3 + b

-2 = 1 + b

-3 = b

Rewrite the equation

y = 1/3x - 3

Please let me know if I did something wrong!

a = ( 3 , 5 )

b = ( 7 , 2 )

[tex]slope = \frac{y(b) - y(a)}{x(b) - x(a)} \\ [/tex]

Now just need to put the coordinates in the above equation ;

[tex]slope = \frac{2 - 5}{7 - 3} \\ [/tex]

[tex]slope = \frac{ - 3}{4} \\ [/tex]

[tex]slope = - \frac{3}{4} \\ [/tex]

And we're done...

Answer:

K - Constant of proportionality

Y/X = K

Step-by-step explanation:

Can’t see the graph but the first point can be calculated. If your first point is (100,78) that’s (x,y), your k = 78/100, $78 US dollars and 100 euros, thus the unit rate is 78/100 = 0.78/1 which means 0.78 dollars equals 1 euro.

Answer:

60

Step-by-step explanation:

Answer: 5t = 400-105

Step-by-step explanation:

Let t= Number of three–pointers Marissa has to average over the next 5 days to reach her goal. .

Goal = 400 three–pointers every week.

Marissa has already shot  = 105 three–pointers

Remaining shots to achieve target (5t) = Goal - (Marissa has already shot)

i.e. 5t = 400-105  (required equation)

⇒ 5t = 295

⇒ t = 59

hence, she need to make 59 shots per day for next 5 days.

Answer:

  6 11/32

Step-by-step explanation:

The two cans of broth used in the recipe total 2·14.5 oz = 29 oz. The number of people John wants to serve is 28/4 = 7 times the number served by one recipe. So, the amount of broth needed is ...

  (29 oz)·7 = 203 oz

Each quart container of broth holds 32 oz, so John will need ...

  (203 oz)/(32 oz/container) = 6 11/32 containers

John needs 6 11/32 containers of broth.

_____

If John must buy the broth, he must buy 7 containers. he will have 21/32 of a container left over after making his soup.

Police officers, whether plain-clothed or uniformed, carry a variety of equipment with them on service calls. Police in uniform carry much more equipment than those in plain clothes, and members of special operations teams, such as SWAT and crowd-control units, carry even more, sometimes including full body armour complete with helmet, leg pads, and shield.

Answer:

7

Step-by-step explanation:

5x = 35

Divide both sides by 5

x = 7

Whenever you have an equation like this, you have to simply divide both sides by the coefficient.

Answer:

Step-by-step explanation:

C = 28

C = 4 + 1/3 D

This means that

28 = 4 + 1/3 D

Subtract 4 from both sides.

24 = 1/3 D

Then to get rid of the fraction, multiply both sides by 3

72 = D

Therefore Drake is 72.

Answer:

y = 6.93

Step-by-step explanation:

Given the Vertex and ficuas of a parabola as :

Vertex (0,0) ; focus(0,2) ; depth = 5 inches

Width of parabolic heater at its widest point :

General equation of a parabola:

4p(x - h) = (y - k)²

(h, k) = Vertex

hence,

h =0 ; k = 0 ; p = 2 ; x = 5

(y - k)² = 4p(x - h)

(y - 0)² = 4*2(6 - 0)

(y-0)(y-0) = 8(6 - 0)

y² = 48 - 0

y² = 48

y = 6.928

y = 6.93

Answer:

Rs. 1076.23

Step-by-step explanation:

The compound interest is given by the formula;

A=P(1+r/n  )^nt

where

A= amount at the elapse of the period

P= principal amount = Rs=4000

r=rate of interest=10% =0.1

n=number of times the interest is applied per time period= 1

t=number of time periods elapsed = 30 months = 30/12 = 2.5 years

Applying the formula;

A=P(1+r/n  )^nt

A=4000( 1+ 0.1/1)^1*2.5

A=4000(1.1)^2.5

A=4000 * 1.2691

A=Rs. 5076.24

Compound interest  will be : 5076.24-4000 = Rs. 1076.23

Answer:

The general rule for estimating is to look at the digit to the right of the digit you want to estimate. Estimating or rounding to the nearest whole number means looking at the digit to the right of the decimal. If you see a digit greater than 5, round up, and if it's less than 5, round down.

Step-by-step explanation:

Answer:

In algebra, like terms are terms that have the same variables and powers. The coefficients do not need to match.

Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power. For example, 8xyz2 and −5xyz2 are like terms because they have the same variables and power while 3abc and 3ghi are unlike terms because they have different variables. Since the coefficient doesn't affect likeness, all

unlike terms
